The COSRX Galactomyces 95 Tone Balancing Essence is a skincare product formulated with a high concentration of Galactomyces Ferment Filtrate, the key active ingredient derived from fermented yeast. Galactomyces Ferment Filtrate contains a variety of components such as amino acids, vitamins, minerals, and enzymes that are beneficial for the skin. Galactomyces Ferment Filtrate works by promoting skin cell renewal and turnover, resulting in a smoother and more youthful complexion. It has been shown to increase collagen production, improve skin elasticity, and reduce the appearance of fine lines and wrinkles. Additionally, Galactomyces Ferment Filtrate has antioxidant properties, helping to protect the skin from environmental stressors and UV damage. The essence also contains niacinamide, a form of vitamin B3 that has been shown to brighten the skin, reduce hyperpigmentation, and strengthen the skin barrier. Niacinamide works by inhibiting the transfer of melanin to the skin's surface, resulting in a more even skin tone. In terms of formulation, the COSRX Galactomyces 95 Tone Balancing Essence has a slightly acidic pH, which is ideal for maintaining the skin's natural barrier function and microbiome. The essence has a lightweight and fast-absorbing texture, making it suitable for all skin types. Its bioavailability allows for efficient penetration into the skin layers, ensuring maximum efficacy of the active ingredients.
